Singer Tamar Braxton has accused a pilot of 'ridiculing' her 'for flying while black' aboard a Delta flight.

The reality star and her sister Towanda had just boarded the plane when they began 'exhibiting unusual behavior', demanding to be allowed to deplane but refusing to take their luggage - a violation of federal law.

Sources told the DailyMail.com that the pair appeared to be trying to delay take off while they made up their minds whether or not to take an alternative flight.

When they failed to take their luggage, flight crews ordered them to sit down ready for take off but the sisters reportedly refused to comply.

It was at this point the pilot got involved.

Towanda posted a video on Instagram of the annoyed pilot lecturing Tamar about the importance of following flight attendants' instructions.

'Here's how this works,' he said in the video. 'My flight attendants work for me.

'They give orders that come from me. So if you get an instruction from a flight attendant, I need to know that you are willing and able to do what you're told to do.

'Are you willing and able to do what you're told to do by a flight attendant? Don't ask me any questions. Answer yes or no.'

Feeling uncomfortable, Tamar and Towanda then discussed disembarking the flight.

'We should get off this plane,' one sister suggested.

'Ok, let's go,' the other replied, gathering their things.

However, Delta confirmed to DailyMail.com that they remained aboard until their destination.

DailyMail.com has reached out to the Braxtons for comment.

Delta told us that the pilot had been forced to intervene because of safety concerns.

'It's crucial for the safety of every flight for customers to be willing and able to follow crew instructions,' a rep said.

'When these customers exhibited some unusual behavior and refused to acknowledge our flight crew's instructions, the captain addressed them directly to ensure the safety and security of the entire flight.'

A Delta rep added that they are in contact with the Braxtons to discuss how the issue was handled.
